The HLB value can be used to predict the surfactant properties of a molecule: < 10 : Lipid-soluble (water-insoluble) > 10 : Water-soluble (lipid-insoluble) 1 to 3: anti-foaming agent [2] 3 to 6: W/O (water in oil) emulsifier; 7 to 9: wetting and spreading agent [2] 13 to 16: detergent [2] 8 to 16: O/W (oil in water) emulsifier
After the required incubation period, when an even lawn of growth is distinctly visible, the MIC value is read where the pointed end of the inhibition ellipse intersects the side of the strip. Etests can be used as an alternative method to determine the minimum inhibitory concentrations of a wide range of antimicrobial agents against different ...
Thiamine is one of the B vitamins and is also known as vitamin B 1. [1] [11] [12] It is a cation that is usually supplied as a chloride salt. [3]It is soluble in water, methanol and glycerol, but practically insoluble in less polar organic solvents.
K ow, being a type of partition coefficient, serves as a measure of the relationship between lipophilicity (fat solubility) and hydrophilicity (water solubility) of a substance. The value is greater than one if a substance is more soluble in fat-like solvents such as n-octanol, and less than one if it is more soluble in water. [citation needed]
Micelle formation is essential for the absorption of fat-soluble vitamins and complicated lipids within the human body. Bile salts formed in the liver and secreted by the gall bladder allow micelles of fatty acids to form. This allows the absorption of complicated lipids (e.g., lecithin) and lipid-soluble vitamins (A, D, E, and K) within the ...

People on dialysis must follow dietary restrictions, making it difficult for them to get the necessary amounts of certain vitamins and minerals to stay healthy. [3] In addition, vitamins and minerals are lost during the process of dialysis. Therefore, dialysis patients are at risk for vitamin and mineral deficiencies.
Example of a label showing the amount of niacin (Vitamin B3), and specifying to be niacinamide in the ingredient section.. As flour fortification started adding niacin in the US, the United States Government adopted the terms niacin (a shortened form of "nicotinic acid vitamin") and niacinamide in 1942 as alternate names for nicotinic acid and nicotinamide, respectively, and encouraged their ...
